How does Winscore calculate finish altitude?

The issue is that the the altimeter setting is usually unknown at the
time of landing but it is almost certainly different for the altimeter
setting at takeoff time. The altmeter error on landing, if still
using the takeoff altimeter setting, may exceed 100 feet even if there
is no significant weather change.

SSA competition rules explicitly state that the finish altitude is
determined based on the most favorable (to the pilot) of the baselines
established at *takeoff*, as well as landing. Guy has verified that
Winscore is doing precisely that. If one leaves their glide computer at
the takeoff altimeter setting, or the glide software is able to
calculate a takeoff pressure altitude baseline and uses that to
determine the finish arrival altitude (as mine does), altimeter error is
simply not a factor...
